SST Consumables Group introduces a new wire, optimized for use on Makino machines with HyperCut technology, including the U3 and U6 wire EDM machines. Together, the wire and HyperCut technology provide superior part accuracy, exceptional surface finish and drastic reductions in cycle time.
This wire technology is a result of collaboration between Makino and bedra. bedra has 125 years of experience in wire manufacturing and is highly regarded for being a pioneer in the development of high-performance, high-precision coated EDM wires. The company smelts, draws and coats its own materials in-house, enabling it to achieve 100 percent process control.
The HyperCut wire boasts high cutting speed, excellent precision and surface quality on Makino machines with HyperCut technology. Initial results of tests using this wire have seen machining speeds increase by as much as 20 percent compared to standard brass wire.
The core material of the HyperCut wire is brass (CuZn40), with an outer coating of gamma-phase brass and a tensile strength (MPa) of 900. This wire offers superior auto-threading and cleanliness. It is available in 0.008-, 0.010- and 0.012-inch diameter on P5, P10, B8 and B16 spools purchased from SST.

- cutting speed
cutting speed
Tangential velocity on the surface of the tool or workpiece at the cutting interface. The formula for cutting speed (sfm) is tool diameter 5 0.26 5 spindle speed (rpm). The formula for feed per tooth (fpt) is table feed (ipm)/number of flutes/spindle speed (rpm). The formula for spindle speed (rpm) is cutting speed (sfm) 5 3.82/tool diameter. The formula for table feed (ipm) is feed per tooth (ftp) 5 number of tool flutes 5 spindle speed (rpm).
- electrical-discharge machining ( EDM)
electrical-discharge machining ( EDM)
Process that vaporizes conductive materials by controlled application of pulsed electrical current that flows between a workpiece and electrode (tool) in a dielectric fluid. Permits machining shapes to tight accuracies without the internal stresses conventional machining often generates. Useful in diemaking.
- process control
process control
Method of monitoring a process. Relates to electronic hardware and instrumentation used in automated process control. See in-process gaging, inspection; SPC, statistical process control.
- tensile strength
tensile strength
In tensile testing, the ratio of maximum load to original cross-sectional area. Also called ultimate strength. Compare with yield strength.
- wire EDM
wire EDM
Process similar to ram electrical-discharge machining except a small-diameter copper or brass wire is used as a traveling electrode. Usually used in conjunction with a CNC and only works when a part is to be cut completely through. A common analogy is wire electrical-discharge machining is like an ultraprecise, electrical, contour-sawing operation.
